RocrazDF If you get the frsky version, it will work with literadio2. Regarding the goggles, if it's 5.8Ghz, it will work.

RocrazDF It's directly related to the kind of flight you do. I often get a bit over 3 minutes with 300mAh and a bit less than 5 minutes with 450mAh.

BG255124832 Yes, those batteries are compatible with geprc tinygo. They are 1S 550mAh with ph2 connectors. And as they are 550mAh, they are very similar to the stock ones (530mAh).

BG255124832 No. Max is 4S.

BG255124832 Yes, it works with this ESC

BG255124832 Yes, it'll work. Any 5.8ghz analog goggles will work. By the way, these goggles will work with the majority of analog quads with 5.8ghz vtx. The controller is a standard 2.4ghz FRSKY d8 controller. So you just need to make sure the drone is set to FRSKY_D.

BG255124832 You have to install your own receiver. In my case I installed frsky xm+ and my radio is Taranis Qx7, mode 2. Works great.

BG255124832 That's easy to get on the Betaflight configurator software. When you connect your quad to Betaflight configurator, it shows you the name of the board. You can also see the name of the board on the CLI tab of Betaflight configurator: type in version, diff all or dump and you'll see the board name. For this quad, that I bought in the end of 2020, it shows up as BETAFLIGHTF4. Mine came with version 4.1.0 (2019-10-16). Today (2021-02-16), latest version is 4.2.8 (2021-02-15).
